Terve Tomi! Very nice design, you have been thinking ;) I'll be in touch via mail, need to know if my measuring application can be squeezed into your design. Best / Brus-Per
Very impressive project, nice! But I've some questions. How do you connected this board to PC (and your another DAC board), what interface/device do you use? As I checked SPDIF allows maximum 24 bit, 192 kHz. And I plan using full 32 bit 768 kHz.
Hi. Sorry for veery delayed reply but as I re-started the channel I will reply anyway. Unfortunately there is not a lot of USB-modules that support recording but miniDSP MCHStreamer is one such board. It doesn't support 768kHz though but up to 384kHz.
@@DexteriLomito You would need an USB board that supports I2S inputs (I2S to USB, recording path). I am not familiar with all options available in the ADAU boards.
Interesting! Would it need a microcontroller to connect the i2c to USB to use as an audio interface? Or can it be clocked by USB? I don't really understand what I am talking about here :-)
First clarification as I'm not sure which one you mean: I2C is a control interface and I2S is digital serial audio. It does not need I2C, everything can be set up with jumper links. But you can also connect microcontroller via I2C to control registers. Audio output is I2S so you need something in there, and one option is I2S to USB module. You need at least master clock from the USB module. ADC can be I2S Master or Slave.
@@kaamostech Ah, sorry! Ment I2S. Yes, have searched for I2S --> USB and only found circuits for DAC:s. Some STM-microcontrollers have stereo I2S in. Maybe that might be an option.
@@rattusrat Some I know of that support both directions are modules by miniDSP and DIYINHK. I have miniDSP MCHStreamer but actually haven't tried it yet.
@@threepe0 The spec sheet may present a visual impression of the harmonic spectrum, but what does that imply? what ADC is used? what kind of load or opamp is the spectrum resolving to? Is lower distortion better? What 2nd order harmonic ratio with 7th or 9th makes the "magic"? musical synthesis? how much of the analysis is being caused by the spectrum anayser itself? how does it sound? i don't know
The PCB looks very nice.
the specs are amazing
Thank you

@@kaamostech Hello whitch ways allows use it for usb. Sigma Studio and adau boards?

And note that most USB to I2S modules only work that way, playback. Only some of them support recording as well.

Are your products still available?
Probably not relevant to you anymore, sorry about that, but for others looking yes they are available still/again :)
You forgot the Shannon-Hartley theorem
Where exactly?
yeah, but how does it sound? You can't measure musicality or magic with a distortion analyzer
sure you can. And unless you're going to Hogwarts, magic has no place on the spec sheet. Neither does 'warmth'
